[ISan] Fix ICE with ISan and -ftree-loop-vectorize

In case we want to vectorize the loop, we can not
rely only on TREE_OVERFLOW flag, while folding the INTEGER_CST,
which represents the step of vectorization.
We still should check TYPE_OVERFLOW_WRAPS flag instead
TYPE_OVERFLOW_SANITIZED flag, because the step could
be already marked as TREE_OVERFLOW == 1.
